Very very Slow boot in Freenas 9.1.1 after root media change

[Skall]

Hello everyone,

I have installed Freenas 9.1.1 in an USB 2.0 4G drive and configured everything on top of that. But I just purchased a new USB 3.0 driver yesterday and did a clean installation of the IMG file to it and imported the backed up configuration file once the new drive is booted up.

After importing backup when I restarted the system, boot up takes about 10 - 15 mins to be ready. It get stucks in few steps:
1. Mounting local file system.
2. start mountd service
3. start smartd service
4. start jails.

Moreover the R/W performance became very very slow once boot is done. Now if I connecte the old USB 2.0 drive same problem arise.

Please let me know how to fix. Any urgent help would be great.

Thanks & Regards
Skall

My system configuration:
AMD embeded CPu 1.6 GHz
2G DDR 3 RAM
1 x 2TB WD Green Drive

Settings:
Compression: Inherit
Dedup: Inherit
Free Disk Space: 400GB

Please let me know whether Dedup: inherit with low RAM caused this. I read it in some FreeBSD forum as follows: http://forums.freebsd.org/showthread.php?t=31999

its not a bug so its in the wrong section, you need to upgrade your ram to atlease 8gb if your using zfs,
with your current setup you need to use another OS without the large requirements that freenas has, also your cpu may seem slow, so you may get poor performance.

i think the community is fine its how freenas is represented in reviews, "use your old pc as a server", but 99% of old pcs dont have the hardware that freenas requires so you get all these similar posts. when users join you should force them to read the user guide pdf before actually using the OS http://doc.freenas.org/index.php/Main_Page

see this example, wiki doco is changed to 8gb ram
"A PC with a minimum of 2GB of RAM. FreeNAS recommends that you have at least 4GB for its ZFS filesystem,"

this is how i learned about freenas, i didnt have a old pc to begin
